Had Prusa come out with an H2D style dual-printhead I would have skipped the INDX myself. There are parts I need to print require internal supports. I'll probably do some multi-color but it's not really something that interests me long term.

Who knows, maybe Bondtech's website is chock-full of technical details today? But given how unbearably slow it is at the moment, none of us could be bothered to look at anything beyond the order page. 😎

BondTech has been around awhile and produce quality goods so it's not exactly a Kickstarter... seems to feel like one though. Anyway, it's been demostrated running on Core One printers for almost 1 year so it's not exactly vaporware.

RE: Bondtech INDX Nozzle Selection

I went for the 4 nozzle option, plus 2 x 0.25. I've got a few  0.6s too - so will probably set mine up with 4x 0.4, 2x 0.25 and 2 x 0.6.

might try adding an mmu3 to one of the 0.4s too.

 

hoping to do some prints with all 3 nozzle sizes in the same print.

Caveat: We don't know whether the firmware and slicer already support different nozzle size in one print. I trust that they will eventually.

But I am very skeptical whether the combination of INDX + MMU will ever be supported. If you really need so many colors online, the 8-tool INDX is available.

Yes, it’s a bit disappointing not to be able to choose your own tools, especially when you order the 8-piece kit. A selection system or a voucher scheme might have kept everyone happy.

 

I think this is because it’s a ‘kit’: as they have 1,200 of them to pack quickly, it’s simpler to include the most popular and most useful version for everyday use: 8 x 0.4 mm CHT nozzles.

 

The good news is that all their tool heads are made of hardened steel, at least.

 

I’ve ordered a few more, just so I can test and use different combinations and get best results :

0.4mm standard for Flex prints (x2)

0.25mm standard for the finest prints like figures or text

0.6mm CHT for quick everyday prints (x2 or more)

0.8mm CHT or 1 mm CHT for hidden structures and rough models

Everyone has different needs; I’m no pro, but I like to experiment and I guess this INDX upgrade will keep me busy for a while 😉

Probably the INDX will be adapted to Voron printers sooner or later but, even then, I wouldn't buy it. Same problem: tools at the front, blocking the view and access to the printer for maintenance and such. Spool management is a problem too if the available space around the printer is very limited, as in my case.

The first printers they demo'd this on where Vorons. Last July they were demonstrating it running on a V0. 

Yes, but for obvious economic reasons Bondtech decided to team with Prusa for developing dedicated kits. On other brands (Voron or whatever), for the time being, you can only buy the INDX parts and the user must design himself the parts for adapting the system. No doubt the Voron community will come with a solution as soon as the INDX hardware is available. Besides, the software shouldn’t be a problem on Klipper based printers. There’re plenty of experienced programmers in the community who will write the macros needed for using INDX toolheads.

Nevertheless, for the reasons explained in my former post, I’ll pass on the current INDX implementations, be it Prusa or Voron. Hopefully, someday somebody will release a INDX based printer designed from scratch. Toolheads at the back, please. Have you seen that picture of the supposed CoreOne-INDX printer with an ugly fence at the front ?, It’s preposterous, you won’t see a thing behind this “iron curtain”,                       

Reallly, it isn’t surprising that a cheapo printer like the Snapmaker U1 gets all the limelight right now. No tinkering required and much more ergonomic than the INDX hybrids,

Many of my prints are 10-12 colours - and my latest one was also 0.4 and 0.2 - so I definitely need more than 8 -  I agree though that it might be tricky getting the MMU3 and INDX working at the same time - although I suspect they will leave firmware support in for both.  

I have a few ideas on how to get more than 8 working one a CoreOne (using two rows of INDX tools and some sort of elevating tool rack - so will probably pursue that too) 

  The main reason for only going for the 4 tool version initially was due to the extra cost of the 8 tool version vs the individual tool costs - plus not being 100% sure what to do about the best way of upgrading to  a CoreOne - as I currently only have an MK3s

RE: Bondtech INDX Nozzle Selection

I saw that you need a standard head (not CHT) for TPU printing. But I would order it later: I will first try it with a CHT... I hope I don't do a stupid thing…

You can print TPU with a HF nozzle. 95A and 64D are fine. For anything else, I would use a 0.6  if the nozzle is CHT.

RE: Bondtech INDX Nozzle Selection

If you work that one out, could you let me know?  (8 tool plus two extra nozzles to justify... 😬 )

Posted by: @hyiger

I may just only install 4 and keep 4 in reserve. Don't know yet. It was "only" $200 extra. Still trying to work out how to spin this with my wife... "You spent how much on parts???"

RE: Bondtech INDX Nozzle Selection

You know what?

As I read again this description: 

Hardened Steel Standard variant

The Stadard INDX Passive Tool is the perfect partner for flexibles. It features a classical, unobstructed nozzle geometry optimized for printing soft materials like TPU and TPE.

By removing the internal core splitter found in CHT nozzles, these variants reduce back-pressure, ensuring smooth, jam-free extrusion for flexibles and sensitive materials. Constructed from abrasion-resistant hardened steel, it maintains the durability needed for abrasive composites while offering the precision required for fine details.

I ask Gustav Bondéus to add a standard 0.4 tool to my Founder Edition command and he agreed to add that to my first order. 

I'm happy 😊

RE:

I suggest you all start with flowers 🌹 (If your wife is like mine, they need to be real ones, not 3d printed - apparently it's a thing 😉 ).  (I've heard that Costco delivers flowers for a good price!)  You can never go wrong with flowers... unless she's allergic to them, then you can quickly go wrong with them!  Maybe dress nice and take her out to eat somewhere nice too.  If you married well, you might be able to dress up and spend the $8.43 you have left after buying your 8 nozzle INDX setup by taking her to Costco for dinner too.  The important part is for her to know feel like you lover her!    YMMV.  

Good luck and please let us know how it works out!

There are many reasons I won't be getting one of these very soon.  I also love my wife more than my printer.  It's worked out pretty well so far.
